cv2实现图像融合_cv2 图像融合

预备知识

 给定两张图像分别为$X_1$和$X_2$利用cv2进行图像融合生成$X_3$$$X_3=\alpha \cdot X_1+(1-\alpha )\cdot X_2$$这两边张图片分别如下所示

程序代码

import cv2
import numpy as np 
alpha = 0.1 #0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9
filename = str(alpha)+r'.png'
img1 = cv2.imread('img/1.png')
img2 = cv2.imread('img/2.png')
img1_resize = cv2.resize(img1, (400 , 400))
img2_resize = cv2.resize(img2, (400 , 400))
img_merge = alpha * img1_resize + (1 - alpha) * img2_resize
cv2.imshow(filename, img_merge/255.0)
cv2.waitKey(0)
cv2.imwrite(filename, img_merge)
